It is the helical antenna that forms spiral fashion electromagnetic radiation section that the antenna of above-mentioned electronic tag can be imagined as, and the main design parameters of helical antenna is to twine times N, screw diameter D, adjacent helix pitch S, spiral angle α.Above-mentioned helical antenna can be divided in the screw shaft normal direction and forms the normal direction mould spiral antenna of greatest irradiation figure and form the axial mode helical antenna of greatest irradiation figure in axis of screw direction.
Read rate in order to improve the group, the radiation field of above-mentioned electronic tag need to present omnidirectional's characteristic in the horizontal surface domestic demand.And the screw diameter (D) that twines actual bottleneck is less than uhf band wavelength (λ), therefore, can be designed to normal direction mould spiral antenna.But gain can be less than general planar antenna.The radiation loop of this spiral fashion label antenna, along with the increase of the overlapping region length of the end in radiation loop, spiral winding number of times (N) can increase to some extent.Though parasitic capacitive reactance does not change in this case, but self-mutual inductance will increase, thereby reduces the resonance frequency of label antenna.
The combination in above-mentioned current supply circuit and radiation loop and the reactive component that produces change by mutual inductance coefficient (M), determine the resonance band of electronic tag with parasitic capacitive reactance and self-mutual inductance.
Fig. 5 is the reactive component X that the length (FL) along with current supply circuit changes
aValue, as can be seen from Figure 5, when the broadside of current supply circuit is 5mm, the spacing between radiation loop and the current supply circuit is 2mm when immobilizing, imaginary number composition (the reactive component X of the equivalent impedance of the electronic tag when the long edge lengths of current supply circuit changes to 15mm from 11mm
a) change curve.At central frequency 0.915GHz place, when long edge lengths changes to 15mm from 11mm, reactive component X
aFrom-j120 to-the j220 rangeability is relatively large.Therefore, can say that in conjugate impedance match be in the inductive coupling power supply mode of purpose, determine reactive component X
aMain design variable be the length of current supply circuit.
Fig. 6 is for when the radiation loop of RFID electronic tag is wrapped on the bottleneck of different-diameter, the reactive component X of variation along with the overlapping field (OL) of the end in radiation loop
aValue.Particularly in the middle of the helical structure in radiation loop, though along with twine number of times, parasitic capacitive reactance does not change, but self-mutual inductance will increase, thereby radiation frequency is offset.Therefore, the label antenna in the utility model by adjusting the winding number of times in radiation loop, in the constant situation of input impedance, is easy to radiation frequency is moved in the middle of the required frequency range.Represent among Fig. 7, when the overlapping field (OL) of the end in radiation loop changes to 15mm from 2mm, imaginary number composition (the reactive component X of the equivalent impedance of electronic tag
a) change curve.At central frequency 0.915GHz place, when the bottleneck of aforesaid liquid container changes to 15mm from 2mm, reactive component X
aVariation is from-j138 to-j152, and to compare rangeability less with the variation of other design variables.Therefore, as can be known along with the bottleneck diameter in the certain limit changes and the impedance of variation, little on the impedance matching property impact of RFID electronic tag.And suitable RFID electronic tag size can be used on the various different-diameter bottleneck liquid management containers within the specific limits.
Fig. 7 is the radiation pattern corresponding to the RFID electronic tag at azimuth and the elevation angle.Wherein, Fig. 7 (a) is take the HUF frequency range as benchmark, the radiation pattern of electronic tag on X-Y plane when different frequency; Electronic tag radiation pattern when Fig. 7 (b) is phi=0 ° and phi=90 °.
Among Fig. 7 a, the position of current supply circuit is phi=180 ° position in the X-Y plane, and the field that greatest irradiation occurs is that its gain is about 1.7dBi between azimuth phi=-90 ° to phi=+90 °.During based on the label antenna radiation pattern at azimuth (phi direction) Graphic Center frequency 0.92GHz place, the gain maximum deviation is 2dBi, and there is not the specific direction blind area in electronic tag, maintains the omnidirectional radiation characteristic in the horizontal surface.
It is the aerial gain radiation pattern of the electronic tag on the Y-Z plane of phi=0 ° X-Z plane and phi=90 ° among Fig. 7 b.As can be known from Fig. 7, phi=0 ° the time elevation angle theta=150 ° and theta=330 ° locate to exist the blind area.The gain inequality that gains between maximum direction and the blind area based on the label at the elevation angle is about 12dBi, shows that the elevation angle changes tag recognition rate is had a direct impact.That is, when the maximum gain of elevation direction (theta) has take current supply circuit as benchmark, the characteristic that center shaft is partially askew about 30 °.And, because near the elevation angle ± 90 °, have maximum gain, so the label antenna below exists liquid etc. to disturb electromagnetic object, also little on the impact of label antenna gain.In addition, in the radiation loop of above-mentioned electronic tag, the far-field radiation major part is to produce in the overlapping field in spiral radiation loop.Therefore, by the lap in suitable adjustment label antenna radiation loop, make its decipherment distance on azimuth direction present omnidirectional's characteristic.
When Fig. 8 is theta=60 ° at the label antenna elevation angle and theta=90 °, the test result of the tag recognition distance that records along with the variation of azimuth phi (X-Y plane), the read write line that uses in the test is commercial hand-held read-write, is that horsepower output is that 28dBm, reading and writing device antenna gain are the circular polarization antenna read write line of 1dBi.
Analyze the test result of decipherment distance as can be known, maximum read distance is 50cm in the time of elevation angle theta=90 °, and maximum read distance is 40cm in the time of theta=60 °.Therefore decipherment distance deviation less in the situation at the identical elevation angle can regard omnidirectional radiation as.And, near overlapping phi=0 ° in radiation loop, recorded maximum decipherment distance.Particularly, when the elevation angle was reduced to theta=60 ° from theta=90 °, tag recognition distance also shortened thereupon.This decipherment distance that occurs along with the variation at the elevation angle changes, and when population of tags is read and automatically communicate by letter with reading and writing device antenna in the identification, should be considered to important environmental change factor.
